Electroencephalography (EEG) is an essential method for conducting research in neurosciences. By measuring voltage fluctuations resulting from ionic currents within the neurons, this technique allows to monitor the brain activity with a high temporal resolution. Classical EEG cap contains several electrodes placed over the scalp and applications goes from event-related potentials, spectral power distribution to sources localization and epilepsy diagnosis.

Brain-Computer Interfaces (BCI) provide a direct communication pathway between the brain and an external device, while bypassing the peripherical nervous system. It is based on a closed-loop design where neural data are processed and classified in real-time while a continuous feedback is shown to the user. BCI research is directed at assisting, augmenting or repairing human cognitive or sensory-motor functions. BCI has been used by locked-in patients to communicate or to control a prosthesis limb.

At Campus Biotech, the EEG-BCI facility supports the scientists by providing the latest EEG systems, shielded recording booths and additional electrophysiological measurement units (EMG, EOG, EyeTracker…). The team also provides research consulting with expertise in multi-streams synchronization, EEG analysis or BCI/neurofeedback design.
